Philadelphia 76ers general manager Elton Brand called Los Angeles Lakers president of basketball operations Magic Johnson on Monday afternoon to apologize for insinuating in a radio interview that the Lakers had called -- unprompted -- to ask permission for Johnson to speak with Sixers forward Ben Simmons, league sources told ESPN.

In the interview with 97.5 The Fanatic on Monday morning, Brand said, "[Lakers GM] Rob Pelinka called me and said that Ben wanted to talk to Hall of Famers after the season; Magic was on the list. He asked for authorization ... I said no."

Brand did not mention in that interview that someone from the Sixers, at the urging of both of Simmons' brothers, had contacted Pelinka first, which is what prompted Pelinka's call to Brand.

The Lakers issued a statement later Monday that read: "To clarify, last November the 76ers sent an email to the Lakers asking if Ben Simmons would be able to speak with Magic Johnson about his Hall of Fame playing career. After receiving the email request from the 76ers, Lakers General Manager Rob Pelinka contacted 76ers General Manager Elton Brand and informed him that Magic could only do so if the 76ers gave him pre-written approval. That was the end of the matter."

NBA spokesman Mike Bass told ESPN on Monday, "The league office is looking into whether any contact took place between Ben Simmons and the Los Angeles Lakers that violated NBA rules."

Brand told ESPN earlier Monday that Simmons simply wanted the Sixers to help him facilitate "chatting with some of the game's all-time greats."

"No issue," Brand told ESPN's Adrian Wojnarowski. "I have a great relationship with Ben and [his agent] Rich [Paul] and we expect him to be a Sixer for a long time. He has taken interest in chatting with some of the game's all-time greats and we're supportive.

"I had brief dialogue with Rob Pelinka, who I've known for a long time, but nothing is planned. Our collective focus is on making a postseason push. Again, we're not sweating this -- end of story."

Later in the day, Brand spoke directly to Johnson to further clear the air, sources said.

Simmons and Johnson are both 6-foot-9-plus point guards. Simmons is eligible to sign his rookie contract extension with the Sixers after the season.
